Thread: Air Cleaner Housing Question

Tweet

I am about to add an hood mounted air scoop to my ride. I am attempting to get more cool air to the carb, but it will not be a true ram air setup.

I have looked at all the types of air cleaners, standard round and oval shapes(open and closed sides), snorkel types (both single and double) and velocity stack style.

My question is this, what is the most efficient aftermarket style air cleaner housing (I also know about K&N versus the world!)?

My gut tells me I should go with a housing that will make the most use of the air coming in through the hood - so a top filter round or velocity stack, would be my first choice. But what the heck do I know!

The best air would be air from outside the car, and not the hot underhood air.... An air cleaner sealed off to the hood and a cowl induction scoop works good, as does ram air. Most everybody runs the open element air filters, but they certainly don't draw in the best air... Cooler air makes better power, so if you can seal off the air cleaner and draw outside air it will make better power.... How much more??? Dunno, but probably not a whole lot. Would be fun to play with it on the chassis dyno some time though...... I'd guess maybe 5 to 7 horsepower difference, maybe more on a hot day when the underhood temps really get up there....

I don't like those velocity stack type air cleaners, for the simple reason that any water that hits them goes straight down the carb throat. Even a car wash can dump a lot of water into your engine, not a good thing.

Maximum filter area is the first thing you want, like 14" diameter by 3 or 4 inches tall. Secondly, you want cold air to it. You can use your hood scoop and glue some firm blocks of foam to the bottom of the hood that would come down and seal off the bottom plate of the filter if you made the plate large enough. Or, you could run a couple of 4" tubes to atmosphere and funnel the air to a closed filter case.

I have a '77 Ford truck that runs a Chevy 355 with a Holley 670cfm carb.
I bought a '69 Boss 429 Mustang hood scoop, that I plan to fit on.
Currently I am using a standard Edelbrock 14" x 3" round cleaner.

I would like to have a different "look" and also bring in more cool air.

I'm thinking about building a ram air intake for the 'maro...But instead of using a dryer vent hose, I keep looking at that gorgeous tubing Pro Z is using on his car...... what the heck, it's just money, right???? Leave it all for the kids they'd just fight over it anyways!!!!!!!
